BACKGROUND Technical Field

The present disclosure relates to a transmission method and device forsupporting power adjustment in a radio communication system, andparticularly to a transmission scheme and a device for supporting poweradjustment in a radio communication system in which a large number ofantennas are deployed on a base station side.

Related Art

Massive Multiple-Input Multiple-Output (MIMO) has become a researchhotspot for next-generation mobile communications. In massive MIMO,multiple antennas can improve communication quality by forming narrowerbeams pointing in a specific direction through beamforming. Since thebeam width is very narrow, the transmission paths through which beamspointing in different directions pass are different, which causes asignificant difference between long-term channel fading experienced bysignals using different beamforming vectors. This difference inlong-term channel fading brings new problems to uplink power adjustment.

SUMMARY

Through research, the inventors found that when the base station adoptsmulti-antenna beamforming based on large-scale MIMO, the adjustment ofthe uplink power is related to the receiving beamforming vector of thebase station, and different receiving beamforming vectors need tocorrespond to different uplink power adjustment processes, the uplinkpower offset for a certain receive beamforming vector cannot be used byuplink transmission based on another received beamforming vector.Otherwise, inaccuracy and performance loss may be caused in uplink poweradjustment based on another received beamforming vector.

FIG. 10 is a schematic diagram illustrating an embodiment of a radioprotocol architecture for a user plane and a control plane, and FIG. 10illustrates a radio protocol architecture for the UE and the basestation equipment (gNB or eNB) in three layers: layer 1, layer 2 andlayer 3. Layer 1 (L1 layer) is the lowest layer and implements variousphysical layer (PHY) signal processing functions, and layers above layer1 belong to higher layers. The L1 layer will be referred to herein asPHY 1001. Layer 2 (L2 layer) 1005 is above PHY 1001 and is responsiblefor the link between the UE and the gNB through PHY 1001. In the userplane, L2 layer 1005 comprises a media access control (MAC) sub-layer1002, a radio link control (RLC) sub-layer 1003 and a packet dataconvergence protocol (PDCP) sub-layer 1004, and these sub-layersterminate at the gNB on the network side. Although not illustrated, theUE may have several upper layers above the L2 layer 1005, including anetwork layer (e.g. an IP layer) terminated at the P-GW on the networkside and terminated at the other e of the connection (e.g. Applicationlayer at the remote UE, server, etc.). The PDCP sub-layer 1004 providesmultiplexing between different radio bearers and logical channels. ThePDCP sublayer 1004 also provides header compression for upper layer datapackets to reduce radio transmission overhead, and provides security byencrypting data packets, and provides handoff support for UEs betweengNBs. The RLC sublayer 1003 provides segmentation and reassembly ofupper layer data packets, retransmission of lost packets and thereordering of data packets to compensate for the disordered receptionresulted by the hybrid automatic repeat request (HARQ).

Embodiment 11

Embodiment 11 illustrates a schematic diagram of a New Radio (NR) nodeand a UE, as shown in FIG. 11. In FIG. 11 is a block diagram of a gNB1110 in communication with a UE1150 in an access network.

The gNB 1110 comprises a controller/processor 1175, a memory 1176, areceiving processor 1170, a transmitting processor 1116, a multi-antennareceiving processor 1172, a multi-antenna transmitting processor 1171, atransmitter/receiver 1118, and an antenna 1120.

The user equipment 1150 comprises a controller/processor 1159, a memory1160, a data source 1167, a transmitting processor 1168, a receivingprocessor 1156, a multi-antenna transmitting processor 1157, amulti-antenna receiving processor 1158, a transmitter/receiver 1154, andan antenna 1152.

In DL (Downlink), at gNB 1110, upper layer data packets from the corenetwork are provided to controller/processor 1175. Thecontroller/processor 1175 implements the L2 layer functionality. In theDL, the controller/processor 1175 provides header compression,encryption, packet segmentation and reordering, multiplexing betweenlogical and transport channels, and radio resource allocation for the UE1150 based on various priority metrics. The controller/processor 1175 isalso responsible for HARQ operations, retransmission of lost packets,and signaling to the UE 1150. The transmitting processor 1116 andmulti-antenna transmitting processor 1171 implement various signalprocessing functions for the L1 layer (i.e., the physical layer).Transmitting processor 1116 performs encoding and interleaving tofacilitate forward error correction (FEC) at UE 1150, mapping of signalclusters based on various modulation schemes (e.g., binary phase shiftkeying (BPSK), quadrature phase shift keying (QPSK), M-phase shiftkeying (M-PSK), M quadrature amplitude modulation (M-QAM)). Themulti-antenna transmitting processor 1171 performs digital spatialprecoding/beamforming on encoded and modulated to generate one or morespatial streams. The transmitting processor 1116 then maps each spatialstream to sub-carriers, which are multiplexed with reference signals(e.g., pilots) in time domain and/or frequency domain, and then uses aninverse fast Fourier transform (IFFT) to generate a physical channelcarrying a time-domain multi-carrier symbol stream. The multi-antennatransmitting processor 1171 then performs an analogprecoding/beamforming operation on the time domain multi-carrier symbolstream. Each transmitter 1118 converts a baseband multicarrier symbolstream provided by the multi-antenna transmitting processor 1171 into aradio frequency stream, which is then provided to a different antenna1120.

In DL (Downlink), at UE 1150, each receiver 1154 receives a signalthrough its corresponding antenna 1152. Each receiver 1154 recovers theinformation modulated into a radio frequency carrier and converts theradio frequency stream into a baseband multi-carrier symbol stream to beprovided to the receiving processor 1156. The receiving processor 1156and multi-antenna receiving processor 1158 implement various signalprocessing functions of the L1 layer. The multi-antenna receivingprocessor 1158 performs a receiving analog precoding/beamformingoperation on the baseband multi-carrier symbol stream from receiver1154. The receiver processor 1156 converts the received analogprecoded/beamforming operated baseband multicarrier symbol stream fromtime domain to frequency domain using Fast Fourier transform (FFT). Inthe frequency domain, the physical layer data signal and the referencesignal are demultiplexed by the receiving processor 1156, wherein thereference signal will be used for channel estimation, and the datasignal is recovered by the multi-antenna detection in the multi-antennareceiving processor 1158 to output any UE 1150-oriented spatial stream.The symbols on each spatial stream are demodulated and recovered in thereceiving processor 1156 to generate a soft decision. The receivingprocessor 1156 then decodes and deinterleaves the soft decision torecover the upper layer data and control signals transmitted by the gNB1110 on the physical channel. The upper layer data and control signalsare then provided to the controller/processor 1159. Thecontroller/processor 1159 implements the functions of the L2 layer. Thecontroller/processor 1159 can be associated with memory 1160 that storesprogram codes and data. The memory 1160 can be referred to as a computerreadable medium. In the DL, the controller/processor 1159 providesdemultiplexing, packet reassembly, decryption, header decompression, andcontrol signal processing between the transport and logical channels torecover an upper layer packet that came from the core network. The upperlayer packet is then provided to all protocol layers above the L2 layer,or various control signals can also be provided to L3 for processing.The controller/processor 1159 is also responsible for error detectionusing an acknowledgement (ACK) and/or negative acknowledgement (NACK)protocol to support HARQ operations.

In Uplink (UL), at UE 1150, data source 1167 is used to provide an upperlayer data packet to the controller/processor 1159. The data source 1167represents all protocol layers above the L2 layer. Similar to thetransmitting function at gNB 1110 described in the DL, thecontroller/processor 1159 implements header compression, encryption,packet segmentation and reordering, and multiplexing between the logicaland transport channels based on the radio resource allocation of the gNB1110, to implement L2 layer functions for the user plane and controlplane. The controller/processor 1159 is also responsible for HARQoperations, retransmission of lost packets, and a signaling to the gNB1110. A transmitting processor 1168 performs modulation mapping, channelcoding processing, and the multi-antenna transmitting processor 1157performs digital multi-antenna spatial precoding/beamforming processing,after that the transmitting processor 1168 modulates the generatedspatial stream into a multi-carrier/single-carrier symbol stream, whichis provided to different antennas 1152 via transmitter 1154 after ananalog pre-coding/beamforming operation in multi-antenna transmittingprocessor 1157. Each transmitter 1154 first converts the baseband symbolstream provided by the multi-antenna transmit processor 1157 into astream of radio frequency symbols and provides the stream of radiofrequency symbols to the antenna 1152.

In UL (Uplink), the function at gNB 1110 is similar to the receivingfunction at UE 1150 described in the DL. Each receiver 1118 receives aradio frequency signal through respective antenna 1120, converts thereceived radio frequency signal into a baseband signal, and provides thebaseband signal to the multi-antenna receiving processor 1172 and thereceiving processor 1170. The receiving processor 1170 and themulti-antenna receiving processor 1172 collectively implement thefunctions of the L1 layer. The controller/processor 1175 implements theL2 layer function. The controller/processor 1175 can be associated withthe memory 1176 that stores program codes and data. The memory 1176 canbe referred to as a computer readable medium. In the UL, thecontroller/processor 1175 provides demultiplexing, packet reassembly,decryption, header decompression, control signal processing between thetransport and logical channels to recover upper layer data packet thatcame from the UE 1150. The upper layer data packet from thecontroller/processor 1175 can be provided to the core network.
